i'm sorry i haven't checked back on this site in ages but the files are compressed in .rar format you need win rar to open them or the newest winzip.
these files contain all the files for the sim.
sorry i thought most people had winrar or something like that. i'll know for the future now._________________________"I understand though unlike me you have a heart and you are powerless to control it consumed by the jealousy you feel toward the student how surpassed you." xemnas kingdom hearts

I thought skins were supposed to be SKN files but these are RAR. When I open them, it just asks me if I want to save it or open it and when I click save or open, it asks me the same question over and over... What am I supposed to do?
